The challenge is that this is a pure Electric pokemon, means it will very likely have to stomach potential incoming Earthquake while at same time being blanketed by ground types.
I am not 100% sure this can actually work in practice, though I can see the actual use case being hard swapping in Bellibolt on a predicted flying, steel or electric hit, then threaten back with a big stab attack meaning you'd be forcing the enemy to swap in an immunity (potentially getting a free turn to hardswap yourself or status them or hit with coverage)
This however relies on several things being present..
1) Being actually able to take 2 hits
1bis) Being able to take a hit and be fast enough to outspeed potential switchins (scarf?)
2) Having coverage and not be another Regieleki case, since without coverage you're literally just being blanketed by ground types and volt absorb
3) Actually having stats to make use of it, as the ideal spread would probably be a bulky attacker rather than pure defensive, it wouldn't matter that he gets a "free +1" if it has chansey tier attack.
We'll see. At least the idea is interesting, either ways.
